Hi, i am trying to compile a minecraft plugin and when i tried to setup shading/relocations, maven shade plugin just decided to flag of the class (which is empty btw, it will be used in the future) and i have no idea whats causing it. Ive found a thread, that it could be lombok, but i have no idea.

The error:

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.2.4:shade (shade) on project LenRoot: Error creating shaded jar: Problem shading JAR /*path*/LenRoot/target/LenRoot-0.jar entry eu/lenithia/lenroot/database/DatabaseManager.class: java.lang.IllegalArgumentException: Unsupported class file major version 65

The class:

package eu.lenithia.lenroot.database;

public class DatabaseManager {
    
}

Is the Java version of your project supported by your local JDK install?

Your maven-shade-plugin is too old it seems

I mean it's probably in your best interest to find out what's causing those warnings
